RESUMING EXECUTION OF AN EXECUTION PLAN IN A VIRTUAL MACHINE

In an embodiment, a query implemented by a first execution plan is executed at a first virtual machine. In response to a move command that requests a move of the first virtual machine from a first computer to a second computer while the first virtual machine is executing the query implemented by the first execution plan at the first computer, an attribute of a resource used by the executing at the first virtual machine is saved to memory at the first computer and a driver source used by the executing at the first virtual machine is saved to the memory at the first computer. In response to a command that requests starting a second virtual machine at the second computer, a determination is made whether the driver source that comprises the state of the partial execution of the first execution plan exists in memory of the second computer.
